MACHINE FOR FIXING HOOPS ON OVAL CASKS OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 619,258, dated February'7, 1899.

Application filed October 23,1895.

To all whom, it may concern:

Be it known that I, J OHANN LEUGERING, a subject of the King of Prussia,Emperor of Germany, residing at Dortmund, in the Kin gdom of Prussia,Germany, have invented new and useful Improvements in Machines forFixing Hoops on Oval Oasks or the Like, (for which I have obtainedLetters Patent in Germany, No. 85,156, dated April 27, 1895,) of whichthe following is a specification.

This invention relates to a machine for fixing or driving cask-hoops onoval casks.

On the accompanying drawings, Figures 1 and 2 are horizontal sections ofthe machine. Fig. 3 is a front elevation, Fig. 4 a vertical section, andFig. 5 a side elevation, of the machine.

The most important parts of such an apparatus, which are collectivelymounted in a rigid frame A, are the following: first, the lower part ofthe press below the ground-level, Figs. 3, 4t, and 5, consisting of apress-cylinder a, with press-piston 1), lower plate 0, on which thecasks are placed, with claw-stops or centering devices d d (Z (Z (Z d dfor the purpose of firmly securing and properly centering the casks uponthe plate 0; then the central parts of the press, consisting of an upperplate f, adjustable in point of height to suit the different heights ofthe casks by means of a central spindle e, and which carries a number ofpress-levers g, arranged radially and radially adjustable to suit thevarying diameters of the hoops, in combination with a lever mechanismand arrangement h 11 k whereby from the workmans position a commonradial rocking or swinging motion to and fro can be effected in orimparted to the press-levers and, finally, the mechanism for working thewhole, consisting of a suitable power-driven pump apparatusl and on theattendant platform suitable and conveniently arranged distributionvalvemechanism for controlling the operation of the press.

That part with which this specification is principally concerned is moreespecially the central part of the press with the rocking press-levers9. (See Figs. 1 and 2.)

The upper plate f, which, like the lower plate 0, is arranged to move upand down in guides of the frame A, is provided with six Serial No.566,614. (No model.)

or more radial grooves or recesses n, in which duplicate slide-pieces 0are arranged to slide radially to and fro. The fulcra or pivots on whichthe pressure-levers g rotate are lodged in these recesses or slideways,through which pass the screwed spindles p for operating the wheels, thesaid spindles carrying on their innermost ends, in the central hollow qof the press-plate, each a bevel-pinion and all these bevel-pinionsgearing simultaneously with a central bevel driving-wheel common to allof them. By means of another pair of bevelwheels, arranged above thehand-wheel, shaft 1' is enabled to communicate radial reciprocatingmovement to the slide-pieces o and the parts connected therewith in theslideways. In addition to this symmetrical movement of the lever fulcraor pivots, effected by the simultaneous rotation of all the screwedspindles 10, there is another movement to be prominently describedviz.,a second movement of the lever-claws a, rocking in wider limits, Figs. 3and 4, for the purpose of giving to the fulcrum-points, and thereforethe claw ends, the position rendered necessary by the oval shape of thecasks. These claw ends, owing to the oblique position of the levers, arelocated under continually wider limits under the influence ofcounterpoise-weights i, secured to the upper or bent ends of the leversg, and therefore they press independently of each other, but withpractically equal and invariable strength, laterally against the ovalcaskhoops.

For casks exactly round it would suffice to rigidly connect thepress-claws directly with the slide-pieces, because they press uponexactly concentric circular points. For casks whereof the cross-sectiononly varies slightly from a correct circular-11 6., imperfectlyroundedcasksnothin g more would be needed than at the most a movable pushing orthrusting iron or claw, spring-controlled, so as to allow sufficientradial movement of the claw.

For oval casks or those of elliptical crosssection, wherein consequentlythe largest and smallest diameters of a cask-section may differconsiderably from one another, it is absolutely necessary, owing to thecharacteristic property of springs in general-viz., that of being ableto exert a constant pressure within small limits, whereby they aredisqualified and rendered inapplicable in this case-to bring into usefor the present purpose a mechanism of a different kind, (such as, here,the

5 levers gand counterpoise-weights t,) whereby a greater range andfreedom of action with constant local lateral pressure is obtained forthe operative claws, because in this case it establishes not onlylinearly, but also dynaml ically, a more than proportionate alterationthan could be attained by the employment of any springs. This regulardynamic efiect increases in importance with the increase in the oval orelliptic form of the casks and grows in I importance the more, forconsideration, that (apart from casks with wooden hoops, such as cementand butter casks) in driving iron hoops on heavy casks, especially whenit is a question of dealing with old casks with hoops 2o loosened bywear and use, when necessarily higher pressure is essential, a positionof the lower lever-claws more and more turned inward is required, thepath described by the claw ends, until it attains the edge of the wheel,becomes ever greater and greater. In order after the fixture of one hoopto pass on to the next, it is necessary to give the lower claws abackward or return motion (away from the cask-hoop)z'. e., to diminishthe action of the counterpoise and relieve its pressure. This iseffected by drawing up the crown-ring h, Figs. 3 and 4:, which isconnected by double links it, the said ring it being connected by alever 71 with a treadle k. On placing a cask on the lower plate a it canspeedily be centered and directly secured to the said plate by theclaw-arms d, which can be readily adapted to any-shaped cask and areoperatively connected with the guide ways 01, tension and thrust bars 61levers (i pivoted on shafts d hand lever (1 and toothed quadrant dHaving now particularly described and ascertained the nature of the saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. In a machine for hooping casks, the combination witha press-head, of press-levers fulcrumed in said press-head, and doublelinks connected to said levers and adapted to simultaneously oscillatethe same, substantially as described.

2. In a machine for hooping casks, the combination with a press-head, ofpress-levers fulcrumed in said press-head, double links connected tosaid levers and adapted to simultaneously oscillate the same, and meansfor forcing inwardly the pressing end of each of said leversindependently, substantially as described.

3. In a machine for hooping casks, the combination with an adjustablepress-head, press levers fulcrumed in said press-head, double linksconnected to said levers, a crown-ring to which the links are connected,a bell-crank lever connected to said crown-ring, and a treadle to whichthe other end of the lever is connected, substantially as described.

4. In a machine for hoopin g casks, the combination with a press-head,ofa press-platform, press-levers fulcrumed in said press-head, weights onthe free ends of said levers, double links connected to said levers tosimultaneously oscillate the same, means for centering and gripping acask, and means for simultaneously adjusting the t'ulcraof saidpress-levers, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

J OHANN LEUGERING.
